Bangshi River (also spelt Bansi) is an important river in central Bangladesh. It originates in Jamalpur, from the course of the old Brahmaputra  and flows past the Madhupur tract. It flows through Tangail and meets the Tongi in Ghazipur. It passes near Jatiyo Smriti Soudho in Savar and falls into the Dhaleshwari. About long, it is not navigable for most of the year except when swelled by the rains of the monsoon.
